I read all of your posts and I have yet to find one that contains information that is right.

I have had 3 AUGs myself, and I am a gundoc. I have worked on/seen over 20 AUGs over time.

I also had P90s and repared some.

YOUR own P90 issue is caused by two things:
Any spring that shoots under 345 fps will cause V3 and V6 to double feed when used with 11.1v or higher. This is because of the way the cut-off lever works and it's relative position to the sector gear.

The stock motor does not offer enough drag to stop the mechbox right away, and the innertia of both motor's rotor and gears is enough to overcome the resistance of weak springs.

That is the reason why you have double feeding issues.

My last P90 was running on 11.1v 1500mAh 20C LiPo. Never had a feeding issue.

Regarding the problem at hand, yes it can be caused by the transfer rod bending out of shape. Same thing can happen on the P90 because it used the same principle to interact with the trigger. Most of the time, the symptom will be a non-working or intermittent full-auto. But a jam (BB stuck/dropped inside the shell) can also cause the rod to bend backwards.
